X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=929adf8838f7765f0bd57235f0e6f365ff628a0d;p=users%2Fhch%2Fmisc.git

bpf, arm64: Remove duplicated bpf_flush_icache()

The bpf_flush_icache() is done by bpf_arch_text_copy() already.
Remove the duplicated one in arch_prepare_bpf_trampoline().
